IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 155,096, dated September l5, 1874 :application filed May 28, 1874.

To all whom it may concern:

' Be it known that I, JOHN MCHENRY, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Carbureters, of which the following is a specification.

This is an improvement in those devices in which the vapor of gasoline or other volatile hydrocarbon is mechanically combined with atmospheric air for the purpose of illumination 0r of heat; and the most distinguishing feature of my invention consists in a provision forutilizing those portions of the gasoline which become condensed or resume the liquid condition within the service-pipes-a defect which, in apparatus of this kind now in use, operates to seriously obstruct the outow of gas, besides wasting the same and imposing considerable labor and watchfulness on those having the apparatus in charge. This utilization I effect by the immediate and constant reconversion ofthe liquefied gasoline into the gaseous form; the object being accomplished by forcing a portion of the entering blast of air through the liquid products of condensation collected in a suitable vessel or reservoir at or near the bottom of the holder-tank, said products being thereby driven back into the carbureter, whence they return, in a diffused or vaporized condition, along with the originally-carbureted air, into the service-pipe. Besides utilizing the condensed gasoline by aid of my improvement, in connection with the carbureter A B C, a light carbureted air or gas can be produced that is suitable for culinary or heating purposes, and which may be consumed in an ordinary gas-burner, and so dispense with a special air-mingling attachment to the gas jet or burner.

My improvement is especially designed for use in connection with the carbureting apparatus which is described in patents to A. C. Rand, granted February 2 6, 1867, and numbered 62,363 and 62,364. The, condensed matters, which in these apparatus', as usually constructed, are a source of care, trouble, and waste, are safely removed from the pipes and utilized by the aid of my improvement.

In the accompanying drawing, Figure lis a vertical diagram of a carbureting apparatus embodying my invention, a portion ofthe carywith a portion of the blast-air.

bureter proper being broken away and thc tank and holder being in section. Fig. 2 represents my sub-carbureter by means of a vertical longitudinal section to a larger scale than Fig. l.

I make of customary or any approved form the following parts, to wit: The Water-tank or cistern A, the floating gas-holder B, the carbureter proper C, the blast-pipe D, and the blower E. Communicating with the blast-pipe D is a pipe, G, which I prefer to have aiiaring or funnel-formed mouth, F. The rim of this funnel being as high as or higher than that ot' carbureter,it follows that gasoline poured into said funnel flows, by pipes Gr and D, (in obedience to its gravity merely,) into the carbureter. A cock, S, enables the closure of the pipe G when not employed for the above purpose. My service-pipe H, toreceive and forward carbureted air from the holder, has its inlet a little higher than the top of the carbureter, and passes perpendicularly downward into a receptacle, I, which I style the sub-carbureter. A little above the sub-carbureter my service-pipe branches, as at H', and, extending upward, H, passes, by a slight ascent, through the tank-Wall, as at Hf. The office of my said sub-carbureter and its accessories is to catch or receive the condensations from the servicepipe H H H H', and to recouvert these liquid accumulations into gas by blending them The pipe ll enters the sub-carbureter near one end of it,

as shown, which end J is partially separated from the other and larger compartment K of the sub-carbureter by a partition, L, which extends from the top to near the bottom of the sub-carbureter. The compartment K of the sub-carbureter is traversed by several perforated horizontal trays or diaphragms, M, which operate to bring the blast-air in minute contact with the uid contained within thc sub-carbureter. To secure this supplementary air-blast, I connect the sub-carbureter I with the blast-pipe D by means of a branch, N, which discharges into the bottom of the compartment K. (See Fig. 2.) From the upper part of the same compartment there extends a pipe, O, which communicates, by flexible tube P, with float Q, that rests, partially submerged, upon the gasoline within the main line in the carbureter C.

form of an inverted -pan partially closed by a perforated diaphragm, T, as shown in Fig. l. Cocks S and S enable the entire or partial closure of either the main blast-pipe D or of the supplementary blast-pipe N.

The operation of my improvement is as follows: Those portions of the suspended gasoservice-pipe which resume the liquid condition flow, by simple gravity, back into the chamber J of the sub-carbureter I, and thence rise to an equal level in both compartments of that vessel. The air which enters compartment K from the supplementary blast-pipe N operates to vaporize the drippings in the sub-carbureter, and to drive the same, combined with air, through pipe O, flexible tube P, and float Q, back into the carbureter proper, where it is brought again into intimate contact with the gasoline contained therein, and finally min gles with the other carbureted air within the holder.

I have selected to illustrate my invention the form of carbureting apparatus successfully employed by me, but may vary the same or other parts of the apparatus in nonessential particulars; for example, an inwardly-opening valve in pipe G maybe used in place of or addition to the cock S, or the in- (See Fig. l.) This float mayl` be composed of metal or other material, in the.

let of said pipe may be closed by a cap or plia- 1 when not in use.

Felt, hair-cloth, or other porous materia'; may be used instead of or in conjunction witl: the perforated diaphragm M, which latter may be more or less in number, as desired. v

While describing the form of my apparatus successfully employed by me, I reserve th option of varying the same,'whi1e retainina the essential characteristics of the improve ment 5 for example, the condense receiving ane'V evaporating compartments may be replacel by two distinct chambers or vessels united b a pipe or passage at bottom, or the eollectioil and evaporization of the condensed matter;- may be effected in a single chamber.

I claim herein as new and of my invention- The receiving and vaporizing box or cham ber, which I have called a subcarbureter, placed within the tank or cistern, in combina-- tion with the carbnreter A B G, the blast-pipe. N, and the pipe O for returning the condensa tions into the carbureter A B G, all combined and adapted to operate substantially as and for the purpose set forth.

In testimony of which invention I hereunto set my hand.
